Magnetorquer misundersanting

1. I have been developing an embedded magnetorquer and I don't how much Am^2 should be the top achievable.

The issue names no file, test, or entry point and only asks how much magnetic moment a magnetorquer can achieve. First clarify the intended documentation change and the required engineering context; completion cannot be verified until a specific scope and acceptance criterion are provided.
